Container Stuffing / Loading Plan Calculator

The Container Stuffing / Loading Plan Calculator tells you exactly how many boxes fit in a shipping container and produces a clear loading plan — boxes per row, boxes per layer, number of layers, total cartons and utilization. Whether you are an exporter planning a shipment or a logistics coordinator costing freight, knowing your load plan in advance prevents under-utilised space and surprise second containers.

Select the container type, enter your carton length, width, height and quantity, and the calculator computes the best orientation and the full packing schedule based on the container’s internal dimensions.

• Four container types: 20ft, 40ft, 40ft High Cube and 45ft with real internal dimensions.
• Automatic orientation: Tries all three carton orientations to maximise the boxes that fit.
• Detailed loading plan: Boxes per row, boxes per layer, layers and total cartons.
• Utilization %: See the share of container volume your load occupies.
• Container count: Whether the order fits one container or needs more.
• Report-only export: Print or save a PDF containing only the final loading plan.
• Free and private: All processing stays in your browser.

1. Select the container type — 20ft, 40ft, 40HC or 45ft.
2. Enter your carton length, width and height in centimetres.
3. Enter the carton quantity you plan to ship.
4. Optionally enter the weight per carton to check against the payload.
5. Review the loading plan — boxes per row, per layer, layers and total.
6. Export the plan — the print/PDF output contains only the final loading plan.

Example 1 – 40ft order: An exporter ships 1,400 cartons of 50×40×35 cm. The calculator shows a 40ft container fits about 1,308 (25 per row, 6 across, 8 layers), so the order is close to one container. The utilisation is roughly 97%.

Example 2 – Comparing to 40HC: The same exporter compares the 40ft standard with a 40ft High Cube and sees the HC fits 1,488 cartons thanks to one extra layer, easily covering the full order in a single container.

• Right-size your shipment: Know exactly how many boxes fit and how many containers you need.
• Optimize freight cost: Maximize utilization and avoid paying for an extra container.
• Plan the warehouse: Give the packing team a clear row and layer schedule.
• Clean output: Export only the final loading plan for your file.
